Which of the statements regarding longitude are correct A) The Longitudes are imaginary semi circular line with same radius. B) The prime meridian divides the earth into two equal halves, the northern hemisphere and the southern hemisphere. C) 180º East and 180º West meridians are opposite to each other on the globe. D) The distance between meridians decreases steadily polewards untill it becomes zero at the poles. Select the correct answer given below.?

Option 3 : A and D

Longitude is a geographic coordinate that specifies the east-west position of a point on the Earth's surface, or the surface of a celestial body.

• It is an angular measurement, usually expressed in degrees.

1. The longitudes are imaginary semi-circular lines with the same radius.
2. The distance between meridians decreases steadily polewards until it becomes zero at the pole.

Mistake Points

1. The prime meridian and the International Date Line create a circle that divides the Earth into the eastern and western hemispheres. 

Hence, longitudes are the semi-circular lines. Which distance decreases steadily polewards and becomes Zero on the pole.
